KRUPP, OF ESSEN-ON-THE-RUHR, GERMANY.

TRANSPORTABLE GUN WITH PROTECTING-SHIELD OFFSET FROM THE TRUNNIONS.

SPECIFICATION forming part of Letters Patent No. 764,477, dated July 5,1904.

Application filed December 21, 1903. Serial No. 186,115. (No model.) i

To all 1071,0111, it may concern..-

of theEmperor of Germany, and a resident of 133 Margarethenstrasse,Essen-on-the-Ruhr,

the gun-barrel and upper carriage (cradle or the like) are ordinarilysituatedin a plane which intersects the gun-barrel near its center ofgravity If the shield is located near this plane, the notch-for hepassage of the barrel and the upper carriage can be of very smalldimensions; but, in fact, the shields nowa-- days are as a rule locatednear the standingplace of the serving crew- -that is to say, rather nearthe breech of the gun-barrel-'-thereby affording the greatest possibleprotection for the serving-crew attainable without increase of theshields dimensions, and consequently its weight, which would bedisadvantageous through which projectiles and fragments of shells canreach the crew behind the shield.

The present invention has for its object to do away with thisdisadvantage incident to guns in which the protecting-shield is offsetfrom the turning axis'of, the gun-barrel and the upper carriage withbutrestricting the range of movement of the barrel and upper carriagenecessary to the elevation and training of the gun. This object isattained'by providing the shield with a roof-shapedapev Be it known thatI, O'r'ro LAUBER, a subject:

ture-blind extending forwardly toward the muzzle of the gun.

One embodiment of theinvention is shown by way of illustration in thedrawings forming part of this specification, in which Figure 1 is a sideview of a gun embodying the invention, several parts being in sectionand the near wheel being removed. Fig. 2 is atop viewof the same. Fig. 3is a front view of the shield. Fig. 4 is a section on line 4 4, Fig. 1,seen in the di ection of the arrow; and Fig. 5 is a detail view of theshield and its blind on an enlarged scale, the shield being in verticalsection.

The gun barrel "A is slidably mounted in the ordinary way on the uppercarriage B,

which rests, by means of a vertical trunnion 6', Fig.4, in abarrel-carrier C, the horizontal trunnions c of which rest at d, Fig. 1,in the trunnion-bearings of the carriagc-body'D. The protecting-shield Fis fixed to the carriagebody in any suitable way. The notch in ;the vshield F for the passage of the upper carriage and the barrel consistsof an upper and broader part E and a lower and narrower part E Figs. 3and 4:. The upper part is of such proportions that it permits themovements of the upper carriage and the/gunbarrel necessary ,i'or thevertical and horizontal adjustment. Thebrjeadth of the lower part Ecorresponds to t'he broadest part of the gun-barrel or the uppercarriage, and said lower. part terminates downwardly in a K broadernotch for the passage of the carriagebody. Located on the side of theshield F toward the muzzle of the gun-barrel is a blind of suitablematerial for instance, sheet- 'steelarranged in such a manner that itcloses the greater part'of the notch E against the entrance ofprojectiles, which, for instance, advance in' the direction of thearrows in Fig. 1.; For this purpose theshapeof the blind G is that ofavaulted roof-tapering in the direction of the muzzle of thegun-barreland the apex-line of which is nearly parallel to' the axis of the boreof the gun-barrel when said barrel is in the position ot' greatestdepression.
